Description

technical field [0001] The invention belongs to the technical field of deep-sea marine energy, and in particular relates to a self-anchored wave energy generating device. Background technique [0002] With the development of the world economy, the surge of population and the progress of society, people's demand for energy is increasing day by day. The vast ocean, which accounts for 70% of the earth's surface area, concentrates 97% of the water and contains a large amount of energy, including wave energy, tidal energy, ocean current energy, temperature difference energy, and salt difference energy. Among them, wave energy, as a clean and renewable energy, has huge reserves, and the use of wave energy to generate electricity has become a research trend in the world's ocean powers. Wave power generation is the main way to utilize wave energy. Far sea areas contain more and richer wave energy resources than near-coast base areas, and a wide range of areas can be selected, which...

Problems solved by technology

[0004] 1. Existing wave energy power generation devices are usually anchored by manually laying anchor piles on the seabed or directly building a concrete platform to achieve anchoring, but it is impossible to install anchor piles artificially on the deep seabed, and it is also impossible to build a platform as a fixation for the power generation device. fulcrum, and the method of anchoring piles or directly building concrete platforms to achieve anchoring is costly, requires manual construction, and is highly dangerous. Therefore, a power generation device that can automatically anchor on the seabed is needed

[0005] 2. The traditional wave energy power generation methods are divided into mechanical, hydraulic and pneumatic according to energy conversion. Among them, the pneumatic type needs a stable platform as an installation support, so it is not suitable for use in deep sea, while the hydraulic power generation process is wave energy- Mechanical energy-hydraulic energy-mechanical energy-electric energy, the mechanical power generation process is wave energy-mechanical energy-electric energy, so the intermediate energy loss of mechanical power generation is lower, and hydraulic power generation is prone to leakage, but traditional mechanical power generation will directly contact seawater As a result, the corrosion rate of the device is fast, so a power generation device that isolates the core components from seawater is needed to solve the problem of short life cycle of mechanical power generation devices

[0006] 3. Most of the current wave energy generation devices can only collect wave energy in the longitudinal direction, the energy collection efficiency is low, and the horizontal wave energy is often not utilized. Therefore, a simple structure is needed to collect horizontal and vertical wave energy.

[0007] 4. The current wave energy power generation devices are usually installed on the sea surface, and the weather at sea is bad, and the devices are easily damaged in extreme weather conditions

[0008] 5. The current wave energy power generation devices are all individual units, and the area covered in the sea is limited, and no large-scale generator group has been established, resulting in low power generation
